If things like Greenpeace eco-surveys don't appear to be on Nintendo's attention radar, it's very clear that employee working conditions are. High suicide rates at a facility operated by one of its outsourcing companies, Foxconn, has prompted Nintendo to start an investigation.

Nikkei reports that the facility, situated in Shenzhen, Guangdong China has apparently had several employees end their own lives but it is unclear exactly how many and over what time period. Foxconn is the core subsidiary of Taiwan's Hon Hai Precision Industry Co. to which Nintendo outsources some of its products, one of which includes the Wii.

What's behind the cause of the suicides is anyone's guess at this point and the most reliable thing to do right now is to wait to see what the investigation uncovers.
